1. GENERAL

This manual provides instructions for the installation of NXP FR10 to FR14 frequency converters in a

cabinet, switchgear, or any other enclosure. If you wish to receive your Vacon NXP drive cabinet-

mounted by the factory contact your nearest distributor.

Vacon NX drives of frames FR10 to FR12 embody 1 (FR10 and FR11) or 2 (FR12) power modules.

NX frames FR13 and FR14 are built of 2 to 4 non-regenerative front-end (NFE) units and 1 (FR13) or 2

(FR14) inverter units. Parallelly mounted chokes are also included in the delivery.

The NXP modules are available as both 6-pulse (standard) and 12-pulse (optional) supply versions.

The NXP product series frames FR10…FR14 comprise the following frequency converters:

*Max ambient temperature +35ºC

The frequency converters can be installed in any enclosure that fulfils the requirements specified in

chapter 3

. In the illustrations in this manual, Rittal TS8 is used as an example enclosure.

Installing NX FR10…FR14 frequency converters in an enclosure involves the following steps:

• Installing the AC choke(s) (chapter 4)

• Installing and grounding of power module(s) (chapter 5)

• Establishing the internal power connections between

a) the AC choke(s) and the power module (frames FR10…FR12) (chapter 6.1) or

b) the AC chokes, the NFE units and the inverter units (frames FR13 and FR14)

• Installing the control unit (chapter 7)

• Preparing for input and output power connections (chapter 8)

• Arranging air-cooling and ventilation (chapter 9).

General instructions for product handling are given in chapter 2. Dimensional drawings are found in

chapter 10.

For more information about the use of the products, refer to the NXC User's manual downloadable at

www.vacon.com. For detailed drawings of the converters installed in Rittal TS8 cabinets, please contact

your local Vacon partner.

3. REQUIREMENTS

3.1 Environmental requirements

Refer to Vacon NXP/C User's Manual (document code ud01011) for information on required operating

temperature, humidity, etc. The User's Manual also states the free space required around the

enclosure.

NOTE! EN60439-1 specifies the ambient temperature for enclosed products at 35°C (24h aver-

age)/40°C (maximum). The ventilation and cooling of the installation room must be suffi-

cient to keep the temperature below this level.

For information on the heat dissipation of the product and the required cooling air, refer to section 9.3

and the Vacon NXP/C User's Manual.

4.1 Installing AC chokes: Frames FR10 to FR12

The recommended location for the AC choke is the bottom part of the enclosure, where it should be

installed close to the rear wall. For a possible later installation of a fuse switch, it may be practical

to install the AC choke somewhat to the left.

Fasten the choke on an assembly plate or using mounting rails.

Figure 5. Installing AC choke

NOTE! An upper support plate must be installed above the choke if the cabinet is transported in

horizontal position. A possible fixed support plate must be equipped with air circulation

holes. See

Figure 36 on page 45.

4.2 Installing AC chokes: Frames FR13 and FR14

Check the needed amount and type of chokes e.g. in Table 14 and in chapter 3.2.2. Place the chokes

on the bottom of the enclosure as shown in Figure 6.

Fasten the choke on an assembly plate or using mounting rails.

NOTE! An upper support plate must be installed above the choke if the cabinet is transported in

horizontal position. The support plate must be equipped with air circulation holes. See

Figure 36 on page 45.

5. INSTALLING POWER MODULE

5.1 Preparing the enclosure

To facilitate a possible future replacement of boards as well as other service work, it is recom-

mended that the power module be mounted on rails.

5.1.1

Mounting dimensions for frames FR10 to FR12

Fasten mounting rails to the sides of the cabinet at distances given under F (from the top) and G

(from the bottom) in the table below. Leave a space (A) between the module and the walls on both

sides for the internal cooling air circulation.

Figure 8. Preparing the enclosure for the power module

The power module should be fastened to the rear side of the enclosure as shown in Figure 10. For

this purpose, install two fixing bars on the rear wall of the cabinet at appropriate levels.

Note the following dimensions that are essential for placing the power module. All dimensions in

mm

A = Minimum distance to the side walls or adjacent components. * = Note that the two cabinets, in

which the modules of frame FR12 are installed, require no clearance between them.

B = Minimum distance from the top of the cabinet; This space is needed for the power cables (see

Figure 14).

C = Module height

D = Minimum distance from the bottom of the enclosure if the AC choke is installed at the bottom

of the enclosure. If the choke is installed in another location, the distance must not, however,

be smaller than what is given in parentheses

E = Minimum distance from the cabinet door; This is to enable the control unit to be installed in

front of the power module. The number in parentheses designates the minimum distance from

the door if the control unit is installed in any other location.

F = Minimum distance from the mounting rails to top of the cabinet.

G = Minimum distance from the mounting rails to the bottom of the cabinet. If the choke is

installed in another location, the distance must not, however, be smaller than what is given in

parentheses

See also the dimensional drawings in chapter 10.

5.2 Mounting the modules

5.2.1

Mounting the power modules for frames FR10 to FR12

NOTE! If the space around the power module is narrow, lead the internal power cables along

the wall and fasten them in brackets before mounting the power module. See chapter

6.1.

Fasten the power module to the rear wall of the enclosure utilising the fixing holes in the frame.

Figure 10. Mounting the power module, FR10

NOTE! If the power module is installed before the AC choke, the centre of gravity is very high at

this stage. Support the enclosure thoroughly during the assembly.
